vWAAS 5.3.3 to 6.2.3 Upgrade Order for CM and WAE

[rick505d3]

Hi, 

Probably a simple answer for someone who has done it or has reference to a docu somewhere. I couldn't find a reference on this specific question. 

We have an existing vWAAS deployment with vCM at 5.3.3 and vWAE's at 5.3.3. This docu is pretty clear on the upgrade path - https://www.cisco.com/c/en/us/td/docs/app_ntwk_services/waas/waas/upgrade/guide/waas_upgrade-60.html#45451 

My question is can the process be like:

    1. vCM    5.3.3 -> 5.5.3 -> 6.2.3

    2. vWAE  5.3.3 -> 5.5.3 -> 6.2.3

Or it needs to be like:

   1. vCM   5.3.3 -> 5.5.3

   2. vWAE 5.3.3 -> 5.5.3

   3. vCM   5.5.3 -> 6.2.3

   4. vWAE  5.5.3 -> 6.2.3

Thanks, 

Rick.

Hi Rick, 

As long as CM has a higher version is good,

Yes, you can have on WAAS environment CM on 6.2.3x and any WAEs on 5.1.x and higher.

So, you can upgrade your CM to 6.2.3 first, and then WAEs from 5.3.3 :

Cisco WAAS Version Interoperability

Consider the following guidelines when operating a Cisco WAAS network that mixes Software Version 6.2.3x devices with devices running earlier software versions:

• Cisco WAAS CM interoperability:
  
  In a mixed version Cisco WAAS network, the Central Manager must be running the highest version of the Cisco WAAS software, and associated Cisco WAAS devices must be running Version 5.1.x or later.
• Cisco WAAS system interoperability:
  
  Cisco WAAS Version 6.2.3x is not supported running in a mixed version Cisco WAAS network in which any Cisco WAAS device is running a software version earlier than Version 5.1.x. Directly upgrading a device from a version earlier than Version 5.5.3 to 6.2.3x is not supported.

Hope that helps.
